Conference Object Citation - WoS: 7Citation - Scopus: 11Longitudinal Evolution of Coachees' Behavioural Responses To Interaction Ruptures in Robotic Positive Psychology Coaching(Ieee, 2023) Spitale, Micol; Axelsson, Minja; Kara, Neval; Gunes, HaticeRobotic mental well-being coaches could be used to help people maintain their well-being, and improve access to mental healthcare. In coaching, the alliance between the coach and coachee is important for the success of the practice. However, this alliance might be negatively affected by interaction ruptures (e.g., the robot making mistakes and the user feeling awkward) that still commonly occur in humanrobot interactions. Therefore, robotic coaches should be able to recognize ruptures occurring during their interactions with human users to guarantee the success of the well-being practice. To this aim, we analyse coachee behavioural responses to interaction ruptures during a robotic positive psychology coaching practice and how these behavioural cues evolve over time. We focus our analysis on a dataset we collected in a previous work, where 26 participants interacted with either a QTrobot or a Misty II robot at their workplace over 4 weeks. We undertake a longitudinal analysis of coachees' multimodal non-verbal cues (i.e., facial expressions, vocal acoustic features, and body pose features) to investigate the contribution of individual modalities for detecting interaction ruptures. Our results show that coachees: i) displayed facial cues of rupture (e.g, laughing at the robot) and suspicion more in the first week than in the last week; ii) talked more and were less silent in the last week than in the previous weeks; and iii) exhibited a higher number of hand-over-face gestures (a cue for self-disclosure) in the last week than in the previous weeks. Our findings aim to inform the development of AI models for multi-modal detection of interaction ruptures which can be used to improve the effectiveness and the success of robotic well-being coaching.Conference Object Citation - WoS: 13Citation - Scopus: 38New Dual Band Dual-Mode Microstrip Patch Bandpass Filter Designs Based on Sierpinski Fractal Geometry(Ieee, 2013) Mezaal, Yaqeen S.; Eyyuboglu, Halil T.; Ali, Jawad K.Dual band dual mode chebychev microstrip bandpass filter designs are introduced for first time in this paper. The proposed filter designs are based on the use of dual mode square slotted patch microstrip resonator. These filter structures are fractally generated using Sierpinski fractal curve geometry applied to the conventional square microstrip patch from 1st to 2nd iteration levels where the first band designed at fundamental frequencies (5.475, 5.45 and 5.4) GHz for each iteration while the second band(8.925, 9.15, 9.05) GHz for each iteration. These filters have been designed using a substrate with a dielectric constant of 10.8 and thickness of 1.27mm. The performance of filter structures, based on resonators has been evaluated using a full-wave based electromagnetic simulator Sonnet software package. Performance simulation results show that these filter structures are compact in addition to good frequency responses and narrow bands gained.
